Excavating and Agriculture Profiles

We at Özkan Steel, can produce single, double, and triple grouser track shoe profiles with improved crack resistance and increased wear resistance to prolong the shoe life and increase heavy equipment performance. All our track shoe profiles are available in rolled condition, in quenched and tempered, or in machined to end product, ready to be mounted.

We can also supply Grouser Bars for regrousing of your track shoes. Grouser Bars are produced with the same grades as the track shoes and can be supplied cut to length and quenched and tempered for improved wear resistance.

Our extensive range of standard and custom design cutting edge (single/double bevel) and grader blade profiles are available in a numerous range of low tensile strength and toughness, carbon steel, and heat treatable boron steel grades. Özkan boron steel grades provide high strength and toughness after heat treatment process and provide significant cost reduction in welding operations, where the blades are welded to the end use area and have enchanted wear resistance. We can also supply machined, heat treated, and shop primer coated cutting edge and grader blades, ready to be mounted.

Please do not hesitate to contact us if you have any further questions.

ANNEALING FOR SHEARABILITY

Annealing for shearability is applied for alloyed quenched and tempered, case-hardening and spring steels that have high hardness in rolled condition.

• Isotropic and more homogeneous mechanical properties are obtained throughout material.

• Impact toughness is increased substantially especially for high-strength structural steels. Impact toughness is much more important for steel constructions nowadays.

• Normalization is a preparation process for subsequent heat treatments of quality steels as quenching and tempering etc. Mechanical properties get more homogeneous and consistent after subsequent heat treatments.

QUENCHING AND TEMPERING

Quenching and tempering is applied for non-alloy and alloy quenching and tempering steels for qualities such as 42CrMo4, 41Cr4, 4340 and C45, C55, C60.

We use water including special polymer for quenching process of alloy steels. We aim to prevent cracking and distortion by using polymer especially for alloy steels.

We can change the polymer concentration in the quenching tank according to required mechanical properties for each quality. Polymer concentration specifies cooling rate and hardening characteristic accordingly at quenching process, thus we can obtain various mechanical properties in the direction of customer requests and market expectation.

We obtain high level of impact toughness in addition to high strength in accordance with international quality standards and customer specifications.

Machining Center

In ÖZKAN's machining center, rolled profiles are being cut to length, machined, drilled, shot blasted, and coated, according to customer specifications and needs. We can meet most of our customers’ demands by processing profile bars up to 12m in our machining center.

All these processes are made within ÖZKAN premises with Özkan personnel to ensure flawless process control and highest end product quality.

For the Excavating and Agriculture sectors, Özkan can provide machined single/double edged flats, grader bars, track shoes, and grouser bars. These products are delivered as end product and ready to be mounted to your machinery.

We are expanding our product range regularly and ready to provide you with profiles not mentioned.

Shotblasting and Priming Facility

ENVIROMENTAL CONDITIONS
Prior to PSP (primary surface preparation), we ensure that the relative humidity is above 85% or the surface temperature of steel is less than 3°C above the dew point. Environmental conditions and steel surface temperature are controlled with Elcometer-319, according to IMO PCPS (performance standard for protective coatings) in every shift.

HEATING SECTION
While applying heat to the profile, the humidity is removed, and the steel must be pre-heated to the appropriate temperature. To acquire appropriate drying, before applying the primer onto the surface of the steel, the recommended steel temperature should be between 30 °C and 40 ° C, depending on the primer type and thickness.

SHOTBLAST SECTION - STEEL CLEANLINESS
The shot blasting section ensures the steel surface is free from visible oil, grease, dirt, mill scale, rust, and foreign matter (ISO 8501-1: 2007 Sa 2½ -very thorough blast-cleaning). There is a cleaning unit and a blasting unit. These units are required for PSP (primary surface preparation) and the abrasives (grit, shot) sprayed on the surface of the material.
To achieve a good protection against corrosion after shop-primer, it is necessary that the material to be painted is applied Sa 2½ - very thorough blast-cleaning. During the preparations for Sa 2½, there will be no oil, grease, or dirt on the surface of the material; there will be no remnants of rust and paint or any other foreign matters.

PROFILE SURFACE
Applying the grit, shot will create the 30-75μm rough surface as per IMO PSPC (performance standard for protective coatings). This roughness will depend on the quality and dimension of the particles, such as grit, shot, etc. and on the grit, shot speed of the spraying. This roughness will create a good adhesive area for the primer, and therefore, the adhesiveness of the primer on the steel profile will be enhanced.
By examining the surface profile with Mitutoyo SJ-301 and Elcometer-224, the ideal surface profile Ry level (the spaciousness between the gorges and peaks) for the primer application should be between 30 and 75 μm.

WATER SOLUBE SALT LIMIT
Water soluble salt limit equivalent to NaCl should be ≤ 50 mg/m2 of sodium chloride as per IMO PSPC (performance standard for protective coatings). By examining the salt contamination with Elcometer-138 (Bresle Method) in every shift, according to ISO 8502-6 and ISO 8502-9.

APPLICATION OF PRIMER
After passing through the shot blast section, the steel proceeds to the priming centre, where the required prefabricated primer is applied through a vertical moving head comprising nozzles spraying the primer on both sides of the steel profile.

DRYING SECTION
The final part of the surface treatment process is for the steel to pass through the heated after dryer. It is advised to do this process in a closed environment for air pollution protection. DFT (dry-film thickness) is measured, according to paint manufacturer spec, with Elcometer-456 at final stage.

Manuel US-Testing

At Özkan, we can offer Manuel US-Testing for profiles being used in critical applications.

Manuel US-Testing is mostly asked for profiles, where they are used as safety material and need extra assurance of the quality of the material.

Manuel US-Testing is being performed within the Özkan premises by certificated Özkan personnel. We can also supply the detailed US-Test certificate of the tested material to our customers for their inspection.
